How do I get a transparent background?

[SuperJMN]

It's rendering over a white background. I would like it to be transparent.

Thanks in advance :D

I made it in my theme:

  var t = new DarkMarkdownTheme();  
  t.BackgroundColor = Color.Transparent;
  ...

  var view = new MarkdownView();
  view.Theme = t;  
  ...
